Application August 21, 1945, Serial No. 611,'71 9 6 Claims. (Cl. 4 -217) This invention relates to ventilated toilets of the general character embodied in my Letters Patent No. 2,389,165, issued November 20, 1945.

The invention of the above identified application provides a ventilating adapter on which the toilet seat is mounted for rising and lowering movements with respect to the toilet bowl, with the adapter being Secured to the bowl and having an inlet opening between the seat and bowl at the rear of the latter, through which odors from the bowl pass into the adapter and from the latter into a suitable stack in the wall of the room, so as to obviate contamination of the air in the room.

An object of the present invention is to provide a ventilated toilet of the above described general character embodying a ventilating adapter which functions in its installed position on the toilet bowl at the rear of the seat, to pivotally mount the latter for its rising and lowering movements and to conduct bowl odors into a wall stack, the adapter being structurally characterized .by means enabling adjustment of the seat relative to the toilet bowl to be efiected longitudinally, transversely and vertically of the bowl sc as to accurately fit the seat and adapter to the bowl for scaling engagement of the seat with* the bowl, irrespective of (1) inequalities in the bowl rim, (2) varations in the spacing of the usual openings provided through the back of the bowl for the pair of stud bolts which are normally utilized to mount the seat on the bowl, and (3) Variations in the spacing between the pivotal mounting brackets on the seat, all to the end of compensating for manuacturing inaccuracies in dimensione of toilets, and rendering the invention capable of practically universal installation on the products of different toilet manufacturers.

Another object of this invention is to provide a ventilated toilet whose ventilating adapter is of simple and durable construction which lends itself to quantity production at a low cost, and which does not require any structural modifi cation whatsoever of standard toilets, to fit the invention thereto, thus inexpensively placing the invention within the reach of the greatest number of users.

With these and other objects in View, the invention resides in the combinations, arrangements and functional relationships of elements as set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawing,

Figure 1 is a plan View of one form of ventilated toilet embodying the present invention;

Figure 2 is an enlarged vertical longitudinal sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a bottom plan view taken on the line 3- 3 of Figure 2;

Figure 4 is an enlarged fragmentary sectional View taken on the line 4-4 of Figure 1;

Figures 5, 6 and 7 are fragmentary horizontal sectional views taken, respectively, on the lines 5-5, 6-6 and 1--1 of Figure 4; and

Figure 8 is a transverse vertical sectional View taken on the line 8-8 of Figure 4.

Referring specifically to the drawing, the invention is shown for the purpose of illustration, associated with a conventional form of toilet fixture composed of the usual bowl B and seat S with or without a cover C. The seat and cover are respectively provided with the usual pairs of hinge brackets n and l l respectively, by which they are pivotally mounted on a hinge pin l2 usually supported =by stud bolts 14 having nuts !5 passing through openings !6 in a rearward extension or shelf l'l of the bowl B, which is fiush with the top surface !8 of the bowl rim as shown in Figure 2. However, in the use of the present invention, the stud bolts !4 are screwed permanently into threaded bores [9 of brackets 20 which are rectangular metal blocks (Figures 4, 5 and 8) and form part of a ventilating adapter designated generally at V.

The ventilating adapter V includes an open ended tubular body ZI of sheet metal which is cylindrical in cross section and is provided with a peripheral, longitudinally extending slot 22. The slot 22 is bounded by a rectangular and hollow base fiange 23 projecting laterally from the body 2l and having an open bottom and an open forward end to co-act with the shelf ll of the bowl B in forming an inlet duct 24 to the body 2l from the space between the seat s and the bowl rim !8 at the rear end of the seat when lowered on the bowl in the installed position of the adapter as shown in the drawings.

Adjacent the threaded vertical bores [9, the brackets 20 are provided with smooth vertical bores 26 slidably receiving posts 21 for vertical adjustment relative to the bowl, and adapted to be clam'ped in a selected adjusted position by set screws 28 threaded into the brackets 20 and rendered accessible to a screw driver through openings 29 in the :base fiange 23 of the adapter as typically shown in Figure 5.

The upper ends of the bores 26 of the brackets 20 are bounded by externally threaded collars 30 projecting freely through transversely extending slots 3! in the top of the base fiange `23 (Figure 7) and having nuts 32, adapted, when tightend,

&519386 to clamp the vent'latng adapter V rigidy in adjusted position to the bowl B through the medium of the brackets 20, which latter will be concealed within the base fiange 23.

At their upper ends, the posts 21 are provided with horizontal sleeves 33 in which are slidably mounted for adjustment forwardly and rear- Wardly of the bowl, cylindrical arms 34 having sleeves 35 receiving the hinge pin [2 between the hinge brackets I and ll as shown in Figure 1. Set screws 36 (Figure 6) threaded into the sleeves 35, rigidly support the hinge pin I 2 in a selected position of adjustment.

Sealing members 31 in the form of curved strips of elastic rubber, are Secured to the underside of the seat S by suitable fastening mem-.

bers 38, and are spaced apart at the front of the seat to provide an air inlet 39 to the interior of the bowl between the seat and bowl rim When the-'scaling membersrest 'uporrth latter in the lowered-'positio'n,of'the'seat as shown-in'Figure 2.

The rear ends' of the sealingmembers 31* tervminate short of the hinge brackets '10, .and

fiangedcovers .doiare Secured to the seat by fas- ,tening members 41" to'fformicontinuations of..the

sealing. members ;to .the. forward end. `of, ,the air inlet 'duet 24' "of the ventilatingadapter. When installingvthe invention, onepehdofthebody 2| is' closed *by a cunshapd 'cap dzjwhereasethe other `end of the body. isconnect,ed bysuitable pipe .fittings 43 to a s'tack (not shown) in the wall of the. room.'leading to the :atticspace or the atmosphere.
